NAIL-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 342,929, dated J'une l,1886. Application filed December 16, 1885. Serial No. 185,810. (Nomodel.)

To all whom it may concern.-

Beit known that I, FREEBORN F. RAYMOND, 2d, of Newton, in the county ofMiddlesex and State of Massachusetts, a citizen of the United States,have invented a new and useful Improvement in Nail-Making Machines, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming a part of thisspecification, in explaining its nature.

The invention is an improvement upon that described in my Letters PatentNo. 317,199, and upon that described in the application of A. O. Townsand myself, filed November 27, 1885, Serial No. 184,048, for nail makingand distributing machines; and it relates especially to the mechanism ordevices for varying the length of nail severed or cut from the wire.

Referring to the drawings, Figure 1 is a view in front elevation of amachine having my invention. Fig. 2 is a view in vertical section andelevation of the portion of said machine to which my invention relates.Figs. 3, 4, and 5 are detail views; and Fig. 6 illustrates amodification.

A represents the frame of the nail-making machine. It supports thefeed-rolls a and a. They are like those described in the saidapplication of Towns and myself, and they are operated by mechanism,substantially as therein set forth, to vary the feed of the wire. Belowthe feed-rolls is a fixed block, o in which is a feedway or passage, afor the wire, and below this stationary block there is arranged themovable block 13, which has a passage or feedway a, in continuation ofthe feedway of the block a. This block B is movable vertically inrelation to the block a in suitable guides or ways, either-by means of aspring, I), which may surround it and bear against the shoulder Z)thereon and against the shoulder b of the block a", or it may be movedvertically by means of a screw, as represented in Fig. 6. For thepurposes of the invention, however, it is immaterial how this block isprovided with a vertical movement. There is arranged to be reciprocatedacross the lower edge of this block, in a suitable passage or guideway,G, in the block 0, the nail cutting and carrying devices, and thesecomprise the block 0, adapted to be positively reciprocated by means ofthe link 0 lever 0 and cam c. This block 0 supports the die-pieces 0which preferably are shaped in side and end elevation as represented inFigs. 2 and 3. They form a passage or feedway, e in continuation of thepassage (4". The die-pieces are fastened to an extension, 0, of theblock 0 by dowelpins 0 passed through holes therein and thecovering-pate c", which is screwed to said extension c, and when thussecured the inclined surfaces 0 of the die-pieces project into theguideway or passage 0. Above the die-pieces c is a wire-cutting plate,D, which has a hole, d, adapted to be brought in line with the feedwaya. This plate D is made vertically movable in the block 0 in any desiredway, and I have represented it as provided with the tongue-projection d,which enters a recess of correspondingshapeintheblock. This tongue mayhave a hole for the reception of a steadypin, and it has a screw-holefor the reception of the screw-spindle d, carried by the block 0, and bywhich it is moved vertically. A checknut, d, may be used for locking thescrew after the plate has been moved to the desired position. The plateD or block B may also have a sleeve or tube, (1*, arranged so that itspassage shall be in continuation of the hole d, and having aslightly-tapering exterior arranged to shut into the slightly-taperinghole of the die-pieces a, so that the tube can have a vertical movementin the passage as the plate D and block B are raised or lowered inrelation to the portion 0 of the block.

In the operation of severing a nail or nailblank from the end of thewire the wire is fed by the feeding devices through the feedway a (0* tothe lower edge of the diepiec'es 0 coming in contact or very nearly incontact with the lower surface of the guideway G. The movement of theblock 0 will cause the cutting-plate D to sever the wire on the line ofits upper surface as the block and plate are moved horizontally past theblock B, and in order to secure (with a proper feed) nails varying inlength it is only necessary to adjust the height or position of theblock B and that of the cutting-plate D in relation to the section orportion 0 of the block. Forinstance, if it is desired to cut a shortnail or blank from the wire, the feed is adjusted to feed thelength ofwire desired, and the cutting-plate D is moved downward in itsholding-block to the desired position, and the block B also moveddownward to correspond or so that its under surface shall come incontact with the upper surface of the plate D, and upon the forwardmovement of the block The result is that the nail will be severed by thecutting action of the cutting-plate D as it moves by or past the end ofthe feedway. If it is desired to obtain a longer nail, the feed isadjusted, the block B is moved upward as well as the cutting-plate D,and as that changes the length of the hole in the carrying-block it isobvious that upon the movement thereof alonger nail or blank will becut. I

The cutting-plate may be made of hardened steel, and the block Bprovided with a hardened-steel die-plate.

To point the nail or blank after it has been severed from the wire, Ihave arranged the pointing-cutters F to project into the guideway 0 upona line with the bevel or inclination of the die-plates. These cuttersare fastened in place by screws or in any other way, and are so arrangedas to sever from the lower end of the nail or blank held in the die suchportions thereof as shall project on either side from the two sidesurfaces of the die, and the waste or sections of the blocks thusremoved drop from the guideway through the escapepassage f. Thesecutters are similar in form and arrangement to the cutters shown anddescribed in my Patents Nos. 31 7,199 and 317,851, and they bear thesame relation to the nailcarrying blockthat is, they are stationary, andare inclined in relation to each other, and the nail-carrying block isarranged to carry or move the nails past them.

The cutters may have any inclination, and may be arranged upon the sameline, or one in advance of the other, as may be desired, and they ofcourse are arranged to conform to the inclination of the lower portionof the die-plate. The carrying-block 0 may be arranged to carry the nailor blank by or past the cutters, and then immediately back to a passagein the throat, arranged in continua tion of the passage a, by which itis discharged from the machine; but the construction I prefer and haveillustrated is adapted to feed the wire blank past the cutters to thethroat G, in which the driver or reciprocating rod g is arranged. Thisthroat G is arranged in a nozzle, 9, and so as to come in line with thehole or passage a of the carrier-block 0 when it has been moved forwardpast the cutters.

The reciprocating rodor driver is operated by a spring and lifting-camor by a cam only,

as may be desired. In the drawings I have represented a spring andlifting-cam, and they are so timed that upon the movement of the nailinto position beneath the rod 9 the rod is released and the springforces it through the passage a of the carrying-blocks, and through indescribed. I would say, however, that for the purposes of this inventionI do not confine myself to a special form of receiving and deliveryblock, but may use any adapted to receive nails from the throat insuccessive order and transfer them for delivery.

I would further state that so far as the cutting and severing devicesare concerned they may be used in a nail-driving as well as in anail-making machine, where it is desirable to make and drive nails ofvarying lengths.

In operation, the cutter-block D and the block B are adjusted to cutnails of the length desired, and upon the operation of the machine thewire is fed by the feed-roll through the feedway cl into the hole in thecutter-block D and dieblock, and upon a horizontal or forward movementof these parts the cutter-block D severs the nail-blank or nail from theend of the wire, and byacontinued forward movement the wire-blank iscarried past the cut ters, whereby its lower end is brought to aposition beneath the rod which is then released to drive or move thenail from the carrier-block through the throat into the feedway-hole ofthe nail receiving and delivery block H. The rod is immediately liftedand the carrier-block returned to its original position to receive thesection of wire which forms the next nail. Meanwhile the nail receivingand delivery block has been operated, as (lescribed in the saidapplication referred to, to bring another nail-receiving hole in linewith the throat, and the operation proceeds as bcfore.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States 1.
